The pond that belongs to this product is in the middle: the backyard pond ringed with cattails. The farm pond where cattle wade in summer. The retention basin at the edge of a neighborhood that someone has decided to care for. The bodies of water that are real and that deserve the same kind of natural treatment as any other water.

Our Bioverse Healthy Ponds 51118 Aquasphere Pro Biodegradable Pond Cleaner - 12,500 Gallons - 3 Pack is your 60 day (2 Month) ticket to clean, clear and balanced water. Each one of the 12,500 Gallon Aquaspheres is perfect for backyard ponds, farm ponds, HOA retention basins, neighborhood ponds, and small lakes up to 12,500 gallons per Aquasphere - or up to 25,000 gallons if you use them together.

THE MAGIC IS IN THE SPHERE - Our AquaSphere®PRO Biodegradable 12,500 Gallon Pond Cleaner is designed precisely for these intimate water bodies. One sphere, four inches across, made from a corn-based polymer certified compostable to ASTM D6400 and marine degradable per ASTM D7081. Simply toss it in. It sinks to the bottom and begins releasing a proprietary blend of beneficial bacteria and enzymes through a patented timed-release system - 24 hours a day, 7 days a week, for a full 30 days. The bacteria consume excess nutrients, break down organic sludge, reduce ammonia, and restore the clarity that clean water naturally has. The corn-based shell quietly biodegrades on the pond bottom when the treatment cycle ends. Nothing to retrieve. Nothing left behind.

TWO 6-INCH SPHERES, BUILT FOR BIGGER WATER - The AquaSphere®PRO 12,500 Gallon 2-Pack from Bioverse Healthy Ponds was designed for this middle tier of water bodies. Each sphere in this pack is 6 inches in diameter — a full 50% larger than the small-pond 4-inch variants — and loaded with a higher concentration of the same proprietary beneficial bacteria and enzyme formula that defines the Healthy Ponds product line. Two spheres per pack. Each one treats up to 12,500 gallons of water for a full 30 days through a patented timed-release system that works continuously from the moment of submersion. Toss them at opposite ends of the pond for even coverage, or deploy one now and hold the second for next month. The corn-based polymer shell biodegrades on the pond bottom when its work is done — nothing to retrieve, nothing left behind.

BIOLOGY WORKING AT SCALE - Six inches of corn-based biodegradable polymer, certified compostable to ASTM D6400 and marine degradable per ASTM D7081, resting on the bottom of a mid-size pond. Inside, beneficial bacteria consume the excess nutrients that drive sludge accumulation, algal blooms, and pond odors. Ammonia drops. Organic matter at the sediment layer diminishes over the treatment cycle. The water above clarifies — not because something was added to suppress a symptom, but because the nutrient load that created the symptom has been consumed. After 30 days, the sphere has done its work. The next one goes in.

WHAT "SAFE" MEANS AT THIS SCALE - The formula inside these spheres is veterinarian-approved and confirmed safe for every category of life that shares mid-size pond water: fish, waterfowl, livestock, wildlife, pets, and people. There are no chemical algaecides, no herbicides, and no synthetic compounds. For farm ponds with cattle access or backyard ponds with visiting herons and neighborhood dogs, this is not a minor point. It is the reason to choose this product over chemical alternatives that require posting, waiting periods, and careful livestock management. Important: treatment bacteria in this formulation are not active below 45°F — pause monthly treatment when water temperatures fall below this threshold and resume when temperatures return to the active range.

THE WATER THAT TAKES CARE OF MORE THAN ITSELF - Mid-size ponds are ecological centers. They regulate temperature, filter water, support populations of insects and amphibians, and provide habitat for birds and mammals that depend on water for their existence. When these ponds fall into imbalance, the effects radiate outward. When they are healthy, they hold things together. The AquaSphere PRO 12,500 Gallon 2-Pack is two months of treatment for a pond that earns that investment — tossed in with confidence, placed where the water needs it most, returned to each month with the knowledge that biology has been at work in the interval.

NOTE - Microbial Products Require Sufficient Oxygen Levels To Function Properly. For Ponds With No Aeration Or Stagnant Water, Excessive Organic Matter Buildup, Dense Fish Populations - Low Oxygen Conditions May Increase The Risk Of Fish Mortality

Recommendations:

• Test Oxygen Levels Before Treatment
• Requires Sufficient Oxygen For Safe Use In Fish Ponds
• Ensure Aeration Is In Place In Fish-Heavy Ponds
• Consider Using A Water Oxygenator If Oxygen Is Low

Microbial Facts:

• Microbial Bioremediation Relies On Oxygen To Break Down Nutrients
• Treatment Temporarily Consumes Oxygen As Organic Matter Is Digested

Pond Oxygen Facts:

• Hot Weather Reduces Oxygen Levels In Water
• Overstocked Ponds Have Higher Oxygen Demand
• Organic Debris Buildup Lowers Available Oxygen
• Shallow Ponds Hold Less Oxygen Than Deeper Ponds
• Low Oxygen = Risk Of Fish Stress Or Loss
